So let's imagine, just for the sake of argument, that I wanted to make to-hit rolls roll-high instead of roll-low, to avoid having to do a lot of subtraction and make it easier to determine what DCV I hit without knowing the DCV of the NPC I'm attacking.
The way I figure it, OCV + 3D6 vs. DCV + 11 would give the same range of to-hit probabilities as the current system, without having to adjust the stats at all. Am I doing this right?
